His co-workers were reportedly supportive at first, but when
Mask's hip-hop videos were
posted online at various financial news sites after "a financial
blogger discovered his Goldman connection," the bank stepped in,
Dealbook reports.

"As more blogs and media outlets picked up his story, Goldman’s
media gatekeepers clamped down. They declined interview and
television requests on his behalf and eventually gave him strict
orders: no more performing, no more recording and no speaking to
the media."

Well, no more performing and no more recording is kind of
antithetical to a career in music, so Mask made a choice: he
chose hip hop.

"At first, it was a cool thing, and everyone at the firm was
like, ‘We’re here to support you.' They knew that was part of my
life. I didn’t do anything to deserve the negative treatment and
the harassment I got," Mask told
Dealbook. "It’s not like I changed the share price."
